HINGE FOR- OVEN DOORS.

original application filed April 2, 1921, Serial No. 458,105.

1922. serial To all 'whom z't may concern.'

Be it known that JosnrH F. LAMB, a citizen of the United States. and aresident of New Britain, county of Hartford, State of Connecticut, haveinvented certain new and useful Improvements in a Hinge for Oven Doors,of which the following is a speciiication.

rlhe present application is a division of my co-pending applicationSerial No. 458,- 105, tiled April 2nd, 1921, and covering improvementsin a range.

rFhe present invention relates to a hinge for oven doors, and has as itsobject to provide a device of this sort having various features ofnovelty and advantage. The present invention contemplates a hinge ofsuoli construction that the door oi the oven is yieldingly held closelyagainst the oven wall or frame, thus providing a tight closure or fittherebetween which will prevent escape of heat or vapors from the ovenabout the edge of the door.

My improved hinge isvery simple in construction, may be economicallymanufactured, and is very sightly; all but the lug or yoke to which thedoor is secured being concealed by the oven frame.

ln the accompanying drawing, wherein l have shown for illustrativepurposes one embodiment which the. present invention may tak-e,

Fig. 1 is a horizontal ysectional View through an oven showing myimproved hinge applied thereto;

Fig. 2 is a fragmentary view taken in horizontal section through thehinge; and

Fig. 3 is a view in perspective of one corner of the oven.

My improved hinge may, of course, be applied to an oven of any suitableconstruetion, the showing oi?` the oven in the draw ing being by way ofexempliiication only. In this drawing, the oven is shown as having anouter shell 10, an inner lining l1, heat insulating material 12therebetween, and a front or frame 13 having a sheet metal7 outwardlyflaring throat 14 which, i1" desired, may be welded to the forward endof the lining 11. 15 designates the oven door which may be of anysuitable construction, in the present instance it having a Divided andthis application filed August 1, No, 578,981.

tapered portion 16 adapted to snugly i'it within the throat 14e. Betweenthe free edge of the door and the front 13 is a suitable latch 17 bymeans or" which the free edge of the door is forced against the ovenframe. This latch may be oi" any suitable construction and is7therefore, not shown in detail in the drawings.

Referring now to the construction ot my improved hinge, it will be seenthat the front 13 of the oven is provided with an apertured hub a inwhich is slidably mounted a hinge member having a stem b extendingthrough the bearing a and a yoke or lugs c on the outer end of the stem.The body of insulating material 12 is re cessed as at d to receive theinner end oi" the stem. On this end of the stem is iixed a collar ebetween which and the hub a is a. spring coiled about the stem Z) undertension so that this spring normally urges the hinge member inwardly.The oven door has a lug g hingedly connected to the yoke c by a pintleit.

With the arrangement described, it will be seen that when the door isclosed, the spring f will pull the hinged edge of the door towards theoven so that the tapered portion 16 of the door will closely or snuglyfit in the throat 14, thus providing a tight closure which will preventthe escape oi gases or vapors. My improved hinge com- 'prises anextremely *few number oi' parts,

each of which is very simple in construe tion. Also, since the springand other parts of the hinge are concealed, the neat appearance of theoven is maintained.

I claim as my invention 1. ln combination, a frame, a door, a hingemember to which said door is pivoted and slidably mounted in said frame,and resilient means urging said member in a direction to bring said doorand frame in contact.

2. In combination, a frame, a door, a hinge member having a stemslidably mounted in said frame, a spring urging said member inwardly,and means for pivoting said door to said member.

3. ln combination, an oven having a tapering throat, a door adapted tofit snugly in said throat, and a hinge provided with means for drawingSaid door inwardlyof the throat yto obtain a Steam-tight fit.

4. In an oven and in Combination, anA oven frame having an aperturedhub, a door, a

5 hinge member ivoted tog' said door and having a stem slldably mountedin the bearing provided by said hub, an abutment 0n the inner end ofsaid stern7 and a coiled spring about said stem and interposed betweensaid hub and abutment Yfor normally 10 urging said stein together withthe door connected thereto inwardly of the oven.
